// RUN: %clang_cc1 -E %s | grep '!!'

#define A(B,C) B ## C

!A(,)!
Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446 2009-12-16 04:14:24 +08:00			`// RUN: %clang_cc1 -E %s \| grep '!!'`
